  • Performed perfectly reliably! Performed perfectly reliably!
So far i like it. I have only ran it for a few minutes to set it up but will give it a proper break-in and test. It should prove to be a valuable piece of equipment to back up my home's power. I had one issue- the assembly instructions were really terrible. The issue is that the assembly diagram is a really small picture, 2 x 2 inches! I had a hard time reading it and seeing what part is what. Also some of the copy references things that aren't on the generator like how the battery cables are attached. For an expensive large ticket item like this they could at least ship with better documentation. Luckily i am mechanically inclined and i figured it out with minimum issues. One word of caution- it arrives bolted to a pallet and you will need a helping hand to lift it up on blocks to install the feet and wheels. It is very heavy so be careful! I have watched videos before hand and i was not surprised by this. Make sure you have a socket set and wrenches for assembly. Also be ready to put air in the tires as they are not fully inflated. Its a beast to move so make sure the tires are filled properly (25-30psi). They also ship it without oil in it but provide enough oil and supplies to do the initial setup and one oil / filter spark plug change. They do not tell you how much oil to put in. You need to check that it is not overfilled. It has a decent dipstick so go little by little and check it as you go I ended up putting in a bit more than half of the bag they supplied. Overall I like the solid build quality and feels like a serious piece of equipment. Update: When hurricane Isaiah came, my town was without power for 5 days. This generator worked perfectly! I was able to run my central air, all lights, fridge, internet, tv and some other items for hours at a time. It performed reliably and with no issues. I discovered that my usage level was burning about .46 gal/hour. which is a bit lower than what they say it burns at 50% capacity. I also ran it enough to do my first oil change and found that it takes 1.7 quarts and the oil filter is easily found in the local pep boys or car parts store. I am very happy with this purchase and glad i have the peace of mind i have this as a backup. ... show more

  • Hurricane Milton provided the first real test of the generator
Being near landfall of Hurricane Milton, I knew we would lose power. I had purchased this generator after Hurricane Ian destroyed the power grid, Milton provided the first real test. Yes, power went out Wednesday night during the peak winds of Milton. I rolled out the generator Thursday morning after winds had subsided and hit the starter. The generator cranked right up, switched the 50 Amp switch and we had power in the house (I had an electrician install a manual switch over after purchasing and a heavy 50 amp cable). The unit powered the central A/C, lights, tv, refrigerator, hot water heater, and pool pump - and never missed a beat. Fuel use - ran the generator for approx 9 hours Thursday, refilled with gas, ran for another 11 hours on Friday, and then had to run for another 3 hours to burn all the fuel from the tank on Saturday after power was restored. I would estimate that running the whole house, we would get anywhere from 13 to 15 hours/tank, more without the a/c. Things that I wish I had bought before - a sound deadening tent to protect the generator from rain and to muffle sound (with the exhaust pointed away from the house the noise wasn't bad inside the home - however, the noise did carry away from the house and I wanted to be considerate of neighbors. Great investment if in an area where you may have extended power outages. While a heavy piece of equipment, it rolls pretty well over hard surfaces. Easy to set up for use, reliable, sturdy, and provides ample power. ... show more

  • 10 hrs of use and charging circuit is dead. Won't start without a jump
Although the generator is working just fine, we are VERY unhappy with Generac and their support. It ran for only 10 hrs after which time the battery failed, will no longer charge and we have to jump start it to keep the job site running. We now have 15 hrs on it (ONLY). Generac's support simply states to take it to a service dealer as per their warranty. IT IS BRAND NEW...and BROKEN. One place we called states they are 7-10 days out before they can look at it, it then takes 3 extra days for parts (since they come from Canada) and we will probably be without a generator for 2+ weeks. We are so done with this unit....we do not care if it runs for 10 years form here on in...the fact it is BROKEN after just 10 hrs is NOT product quality nor does Generac really care. We will NEVER buy another Generac product from here on in. We did nothing wrong, just used it (usually with 1 120V circuit plugged in and that's it. HORRIBLE product satisfaction. We will NOT be buying such items from Amazon again, unless Amazon sells them...no 3rd party sellers... The run around we have gotten for the last 2 days about the servicing and Generac's support is very very uncalled for nor realistic. We have a job to do and can't get it done due to a failed product. Broken products like this REQUIRE immediate attention...not a run around. ... show more

  • A big serious generator that requires some serious set up
Delivers the power we need for our heat pumps, well, fridge, microwave, internet and some lights. Started right up after set up. Overall I am very happy with it. It is very loud and very heavy. We had an electrician set up a transfer switch and a heavy duty cable so we can switch from utility power to generator power for the essential items we needed. BE ADVISED when it is delivered it comes bolted to a pallet and you have to unbolt it and figure out how to lift the thing to attach the wheels. The unit weighs about 450lbs! I used a 2x4 to lever it up and some blocks to hold it up while I attached the wheels. I recommend getting a friend to help with this. The directions are not as well written as I would have liked. Now that it is all assembled it is still a bit of challenge to move around given the weight. But hey, this is not a generator for quick casual use. This thing is serious. I can’t really comment on tech support as I haven’t had to use it. I did like the free scheduled delivery - this made life easier. Love the electric starter. ... show more

  • Poor customer service and owners manual is limited in scope.
The Generator arrived with no gas cap. The shipping company left it in the driveway, as they were unable to move it to the garage. The assembly instructions are rudimentary at best and I had to watch a Youtube video just to know how to assemble. It arrived with two bags of oil and nothing in the manual says how much to put in, so in my experience, machines normally arrive with the correct amount of oil, so when I added both bags, and when I checked the oil it was 4 ounces over full. This was my fault, as I should have looked on the internet, but why not just ship the right amount. I have not used the Generator yet, but Generac needs to send a more detailed assembly book and a much better owners manual. The missing gas cap is also completely uncalled for, especially when there is an inspected by sticker on the unit. ... show more

  • The Very Best !
This is a really great generator that powered our lights, TV, fridge, other small appliances and in our small house our air conditioner. We still had enough power to run some lights, a fridge, a TV and a fan for two of our neighbors, which by sharing, considerably lowered the cost of the gas. If you read the instructions and learn how to care for it and are diligent about it's maintence it will last you for many, many, many years without problems. It is VERY heavy. it has two wheels so if you are moving it on a hard surface it's okay but more difficult to maneuver on grass unless the tires are pumped up hard. It is noisy so we put it away from the house. This is a very fine machine and if you buy it and maintain you will have no regrets. ... show more

  • Better than I expected and my expectations were pretty high.
Arrived to the door. The driver moved it into the garage for assembly. I could make a couple of changes to the assembly directions but you can make it through without a problem. Started quickly and smoothed to a nice idle in no time. I certainly didn't expect an extra air filter, oil filter, and spark plugs but those were included. Very nice touch. I wired my mains panel up with a convenience outlet just outside the house. Turned the main breaker off and I was able to run everything in the panel [including two heat pumps, the well, a pond pump and all a circuit in every room, basement and garage. Still plenty of leftover capacity. No dimming of lights [no voltage drops] when heat pumps or well pump kicked in. I was missing a few parts, but when I called Generac they promised to send the parts out right away and did. I could have gotten by with the 10000, but for a few hundred bucks more I couldn't pass it up and I have no regrets. ... show more

  • I wanted something that could easily power a 50A circuit for extended periods of time ...
This thing is a workhorse. I purchased this because we lost power for 6 days this past fall and our home is on a well system. No power means no water for us. I wanted something that could easily power a 50A circuit for extended periods of time while remaining fuel efficient. I immediately had buyers remorse due to the high cost of the unit until we had another power outage 1 month later. This time the power was out for 9 days. The large 16 gallon tank is awesome! Especially coupled with it's automatic idle control mode. This mode vastly improves fuel efficiency by throttling back the motor based on load. We were able to run our 50A circuit which included a well pump, sump pump, water filtration and softening system, refrigerator, freezer, overhead lights in our great room, and some kitchen receptacles including a TV! As long as we were smart about our power usage, the 16 gallon tank could last us as long as 14 hours! We love this generator, it was worth every penny. The only downside is that it is quite loud under full-load, but we were able to locate it in an area that prevented the sound from traveling into the home. ... show more
